2. Installation, Piping, and Wiring
WARNING
Make sure no one turns on the power switch while work is being done on the pump. Be sure to turn off the
power switch before you start any maintenance/repair work concerning the pump. If the working site is
noisy or under conditions of low visibility, you should display a notice which clearly states “POWER
OFF(MAINTENANCE),” near the power switch in order to inform other personnel about the situation.
Power ON executed by any other person than the operator/service personnel may result in a serious
accident. The operator must take special precautions to avoid accidents.
Only the operators/service staff who are adequately trained in safe handling procedures should be in
charge of the related electric arrangement and control of the power source. Iwaki takes no responsibility
for injury to person or damage to assets which results from a failure to observe this instruction. Consult
Iwaki, an Iwaki branch office, or an Iwaki distributor as necessary.
When you feel or notice any danger or abnormal condition during installation and other set-up work, stop the work and
go back to the very first step.
2.1 Installation
[1] Pump installation position
¡
Flooded suction system
Set the pump as close to the liquid supply tank as
possible.
Caution
Employ a flooded suction system for feeding a liquid
at higher temperatures than room temperature or for
a liquid circulation system.
¡
Suction lift system
Set the suction side piping in accordance with the
self-priming capacity and as close to the liquid sup-
ply tank as possible.
*
Self-priming capacity :
FS-15 : 1m
FS-30 : 2m
FS-60 : 2m
Caution
The self-priming capacity above is based on a pump operation at the max. stroke speed using pure water at room
temperature. The suction height differs with the liquid’s characteristics, temperature, and suction pipe length. For
detailed information, contact Iwaki.
[2] Installation foundation
Select a flat and rigid foundation (such as a chassis) for installation, to avoid twisting motion or vibration.
[3] Direction of pump
Direct the discharge port upward and the suction port horizontally. Use anchor bolts to fasten the pump firmly in
position.
[4] Bolt tightening
Tighten the bolts on the housing upon installation by applying the following fastening torque.
